When I bought my SuperUniti I was told that the speaker cables needed to be min 3m per cable for impedance reasons. A few upgrades later and I have a NAP300DR, does the 3m rule still apply?
I’ve checked the manual and can’t find any ref to it, I’d like to get Chord Sarum T, 2m lengths so I don’t have lots of coiled up cable and to save ££££
The reason for the cable length is to have the right inductance load, the 3.5m minimum length only applies to NACA5, this has an inductance of 1uH per meter = 3.5uH - more is better.
Does a length of Chord give the same inductance, as suggested (above) ask them, I will be surprised if you get a straight answer.
Another thing to consider, the Chord Sarum T & Naim Super Lumina cables are of similar construction, both screened single conductor pairs & I suspect the inductance will be similar (same ball park)
Naim do not sell a length less than 3m (I assume to get a minimum acceptable inductance) , whereas Chord’s shortest appears to be 1.5m.
Naim Super Lumina 3m = £2037 GBP
Chord Sarum T 3m = £3600 GBP
You should be exact otherwise you are not getting the optimum results. The Exact length is 3.4765m. Please be exact otherwise impedance will destroy your sound quality. Hope that helps.
For NAP 250DR it is completely different. Lengt shpuöd be exactly 3,233 because of the earth rays and magnetic field.
I use the s4 cables from Viablue for ~350€ a pair for 3m. Which, I think, is fairly priced. So a german company sells well reviewed, good quality product for 350€ and makes a profit … how much difference in material and „engineering“ cost is there to justify prices in the thousands. Everybody uses marketing words like highly complex, painstakingly, innovative… but there is nothing special. Like focusing on a micro detail and talking about it like it is something important …
Also if you notice on shows they tell you what you will hear when you test an expensive cable and how much better it is, priming you to hear differences where there are none. And because of priming and expectations (it is expensive, this is why is good) you imagine stuff.
I would just buy whatever I like and can easily afford. Why spending so much energy over a cable?
